Activity No. 4. Getting acquainted with the essential terms in studying environmental toxicology and health, evolution, ecosystems, and interactions will not be sufficient. What matters is that you should be able to identify and discuss different toxic elements present in the environment, whether naturally occurring or human-induced. It is also important to determine the route and persistence of these pollutants to develop measures and mechanisms to reduce the risk of potential food contamination and other agricultural resources. Now, I will require you to explain your answers thoroughly. 1. What is biomagnification? Why is it essential in toxicology? 2. Differentiate acute effects from chronic effects. 3. Identify and discuss comprehensively the components of risk management. 4. How are toxic elements being deposited in the environment? Can these toxic elements/ chemicals contaminate the food chain
